Fly
Nematocera (includes Eudiptera)
Brachycera
True flies are insects of the order Diptera (from the Greek di = two, and ptera = wings). Their most obvious distinction from other orders of insects is that a typical fly possesses a pair of flight wings on the mesothorax and a pair of halteres, derived from the hind wings, on the metathorax. (Some species of flies are exceptional in that they are secondarily flightless). The only other order of insects bearing two true, functional wings plus any form of halteres are the Strepsiptera, and in contrast to the flies, the Strepsiptera bear their halteres on the mesothorax and their flight wings on the metathorax.

Famous quotes containing the word fly:
“The son will run away from the family not at eighteen but at twelve, emancipated by his gluttonous precocity; he will fly not to seek heroic adventures, not to deliver a beautiful prisoner from a tower, not to immortalize a garret with sublime thoughts, but to found a business, to enrich himself and to compete with his infamous papa.”
—Charles Baudelaire (1821–67)
“All places were now become irksome to her. She found it impossible to fly from infamy, unless she could at the same time fly from herself.”
—Sarah Fielding (1710–1768)
“Lame as I am, I take the prey,
Hell, earth, and sin with ease o’ercome;
I leap for joy, pursue my way,
And as a bounding hart fly home,
Through all eternity to prove,
Thy nature, and Thy name is Love.”
—Charles Wesley (1707–1788)
